Device for programming of recording by reference signals recognition

Abstract

A driving device for driving a recording apparatus for selective recording of audio/video sequences, which is to actuate the recording apparatus at a precise instant of a beginning or of an ending of the audio/video sequence to be recorded. The driving device reduces picture datum from at least one reference picture belonging to the sequence to be recorded and a memory stores the reduced reference picture datum. A comparator compares the stored reduced reference datum with reduced picture data picked up from the set of picture sequences. A controller controls the recording apparatus to be activated to begin recording at the time the comparator detects a recognition of a picture similar to the stored reduced reference datum in the set of picture sequences.
